IMPROVEMENT IN SYRINGES.`

Specication forming part of Letters Patent No. 123,587, dated February13, 1872.

To all whom it may concern: v

Beit known that I, WILLTAM B. SNYDER, of Bridgeport, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Urethral Syringes, of which the following is aspecification:

The objects of my invention are to adapt the syringe to the male organto prevent injections from entering the bladder while acting freely onthe uretha; to hold the instrument securely in position; and to renderits parts easily detachable.

My improvements are specifically designated in the claims hereinafterset forth.

The accompanying drawing represents the best form of instrument nowknown to me. Some parts of my improved syringe obvious' ly may be usedwithout the others, or adapted to other constructions of syringes, andtheir details may be varied to some extent without departing from thespirit of my invention.

Figure l represents a view in perspective of my improved instrument.Fig. 2 represents a section through the injection-pipe, showing also thearm for -holding the clamp. Fig. 3

Arepresents a view of the clamp.

The body A of my syringe is provided with a male or female screw," a.,to adapt it to any of the syringes now in ordinary use. Aninjection-pipe, A', is connected at or near one end with this body, itsother end being provided with a bulb, al, to close the urethra betweenthe bladder and diseased part when inserted. Perforations c2,'near thebase of the instance a shoulder, b', is formed on the arm B, near itsend, and an annular groove, c,is also formed in it still nearer the end.A sleeve, c', on the clamp-bar C, ts on the arm B between this shoulderand groove.

A clampor by a screw-clamp.

plate, D, is also provided with a sleeve, d, which iits over the othersleeve,`c, turning freely thereon, as the latter does on the arm. Avspring', E, on this plate enters slots in sleeves c and d, and takesinto the groove c on the arm, thus clamping the parts securely together,and yet leaving them free to move and easy to detach. The clamp-'arm Cforms an elbowlever, its bent arm passing through a slit in the plate D,and bearing against one edge ot' said slit, so as to produce suicientfriction to hold'it in position.

Many modifications of the details of this clamping apparatus wouldobviously suggest themselves to any skillful maker of instruments of`this class. For instance, the parts C D might both be made in the formof bars or rods, or spring-arms, or have'a spring connection, instead ofa hingejoint. The arm I) might be hinged at its elbow, and provided withaspring, or it might be provided with a ratchet or other device to lockit to the other member of the clamp. The arm B might also be attached tothe body A by means of a collar iittin g thereon, For various reasons,however, I prefer the form shown.

The operation of my improved instrument will readily be understood fromthe foregoing description. The tube A is inserted in the uretha, thepenis is passed through the clamp t0 the desired extent, and thencompressed by bringing the parts C l) together. The injection is thengiven in the usual way.

I claim as my invention- 1. The combination, with a urethral syringe, ofa clamp, substantially as hereinbefore set forth.

2. The combination of the body, arm, and clamp, substantially ashereinbefore set forth.

3. The combination of the clamp-plate and clamp-arm, substantially ashereinbefore set forth. 4. The combination of the grooved arm, slottedclamp, and holding-spring, substantially Y as hereinbefore set forth.

In testimony whereof I have hereunto subscribed iny name.'
